"The sky started out with residual clouds from a couple of thunderstorms and slowly cleared through the evening, though never completely. Very strong winds at times (15-20+ mph). Excellent sky quality at this location with only the minor skyglow from nearby Torrey visible. No visible lights from the histroic Fruita area in the park, though lots of vehicle traffic on the main highway and even occassionally at Panorama Point."

"Smoke plume to west, some high cirrus, transparency fair. Second set best of night"

"Very good detail in the Milky Way.One side of sky much brighter due to Vernal Utah. Bathroom light bright. Fire south of Rangley about 30 miles away, otherwise clear."

"Horizon blocked. Borlte 3 due to city lights beyond canyon wall."

"Moab and Green River barley visible to the E and NE and the Greater Salt Lake City area also just visible to the north. There is some residual haze along the distant horizon from the very hot temperatures. Very good detail in the Milky Way and stars visible down to almost the horizon to the south. Some airglow obvious all around (especially to the west), but otherwise a fairly pristine night sky."

Airglow moderately bright, considerable detail in the Milky Way."
